如何阻止GetOpenFileName加载DLL

Question

我用GetOpenFilename来获取一些文件名

const int BUFFER_SIZE = 8192;
char* filenames = new char[BUFFER_SIZE];
filenames[0] = 0;

OPENFILENAME ofn;
ZeroMemory(&ofn, sizeof(ofn));
ofn.lStructSize = sizeof(ofn);
ofn.hwndOwner = ::GetActiveWindow();
ofn.lpstrFile = filenames;
ofn.nMaxFile = BUFFER_SIZE;
ofn.lpstrFilter =
   "Quotes\0*.json\0"
   "All\0*.*\0";
ofn.lpstrCustomFilter = NULL;
ofn.nMaxCustFilter = 0;
ofn.nFilterIndex = 1;
ofn.lpstrFileTitle = NULL;
ofn.nMaxFileTitle = 0;
ofn.lpstrTitle = "Web File Import";
ofn.lpstrInitialDir = "T:\\WebPending";
ofn.Flags = OFN_ENABLESIZING | OFN_ALLOWMULTISELECT | OFN_EXPLORER | OFN_FILEMUSTEXIST | OFN_HIDEREADONLY | OFN_PATHMUSTEXIST | OFN_ENABLEHOOK;
ofn.lpstrDefExt = "json";
ofn.lpfnHook = DDWebImport::Hook;
bool rv = ::GetOpenFileName(&ofn);
// Check the error if you have copied this code to another dialog and it returns immediately without popping up a form
DWORD err = CommDlgExtendedError();

我使用的是一个带有SSD的核心i7，这需要超过8秒的时间来显示文件。当我查看调试输出窗口时，

我如何阻止GetOpenFilename从加载DLL，如directx，git，乌龟git，凹槽，git驱动器。有了这么多的文件名，它们需要很长时间才能加载，而不需要仅仅查看一堆文件名。

Answer 1

我要找的真正答案是在Slow loading of symbols during call to CoCreateInstance in VS 2012

基本上将dll排除在工具/选项/调试/符号中加载，查找所有声称无法找到或打开pdb文件并将它们添加到列表中的dll。
